To find out the electronegativity of each pair, work it out by listing them.
H = 2.2
S = 2.1
N = 3.0
Cl = 3.0
O = 3.5
C = 2.5
H – S -> 2.2 - 2.1 = 0.1
H – Cl -> 2.2 - 3.0 = -0.8
N – H -> 3.0 - 2.2 = 0.8
O – H -> 3.5 - 2.2 = 1.3
C – H-> 2.5 - 2.2 = 0.3
So, the pairs that has the highest electronegativity is H-Cl and N-H.
Answer:
Explanation: A cubic centimetre (or cubic centimeter in US English) (SI unit symbol: cm3; non-SI abbreviations: cc and ccm) is a commonly used unit of volume that corresponds to the volume of a cube that measures 1 cm x 1 cm × 1 cm.
Answer:
How do we know what the temperature of the Earth was in the past? - One way to measure past temperatures is to study ice cores. Whenever snow falls, small bubbles filled with atmospheric gases get trapped within it. In some places, so much snow falls that the older layers become buried and compressed into ice, locking away air bubbles in ice sheets and glaciers
What is the relationship between CO2 (carbon dioxide) and temperature on Earth? - When the carbon dioxide concentration goes up, temperature goes up. When the carbon dioxide concentration goes down, temperature goes down.
What is the greenhouse effect? - the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
Why are global sea levels rising? - Global warming is causing global mean sea level to rise in two ways. First, glaciers and ice sheets worldwide are melting and adding water to the ocean. Second, the volume of the ocean is expanding as the water warms.
The answer is 50 kcal by the formula of 10% - 500kcal x .1 = 50 kcal it is the approximately chemical energy that can contain by the secondary consumers.
1%- 500,000 kcal x .01 = 5,000 kcal for producers.
10%- 5,000 kcal x .1 = 500 kcal for primary consumers.
10%- 500 kcal x .1 = 50 kcal for secondary consumers.
10%- 50 kcal x .1 = 5 kcal for tertiary consumers.
Each trophic level receives less and less energy, so fewer organisms can be supported at higher levels.
10% of energy gets passed to next level in form of chemical bonds and 1 decimal place.
To work out the time taken to travel a certain distance a ta certain speed, we divide the distance by the speed.
So, 3/5 = 0.6 hours. To convert this to minutes, we need to work out 0.6 of 60. We can do this by simply multiplying 0.6 by 60, to get 36 minutes.
